Why did Bristol Palin decide to sign on for next season's Dancing With the Stars?
"I just wanted to do it because it's so fun," she told UsMagazine.com at a DWTS press conference Monday night. "It's positive and it's a good competition. I wanted to step outside my comfort zone and have a good time."
Her mom, former vice presidential candidate Sarah Palin, was supportive as well.
"She's always been my No. 1 fan," said Bristol, 19, who will dance with two-time champ Mark Ballas. "Of course, she'll be down here [cheering me on]."
But she won't baby-sit grandson Tripp, 19 months, while Bristol is rehearsing. Said Bristol, "She'll be traveling the world doing speeches and stuff."
Bristol said her biggest personal challenge will be "just showing my personality and moving my hips!"
Who is she most worried about on the dance floor? Dirty Dancing star Jennifer Grey and singer Brandy!
"They both have some dance experience," she said. "But everyone's so good and I'm so happy to be a part of it."
She told Us she was most psyched to meet Florence Henderson, whom she called "an icon."
Added Bristol, "The pro athletes are pretty cool too."
As for those DWTS costumes, Bristol told Us, "We did our title shoot today, so I got all glammed up and stuff, but I'm definitely excited to wear all those. I know that mine will be the most conservative — I will be the most dressed. That's how I am and that's how I want to dress. But it'll be good, all the rhinestones and spray tans, that will be fun."
